I am spending my first week in my 2016 36ckts. I seem to be having fan issues. When I turn on the microwave exhaust fan, most of the air blows into the kitchen rather than outside. I asked the dealer tech about this, and he told me that I have to open the outside vent, which is high up on the unit. I got a ladder to reach the vent, but it does not appear to have a mechanism to open any further. In looking in the microwave manual, it only references that the installer should make sure the vent flap moves freely. To me this means the outside vent does not open, but there is a flap that should open automatically in the unit. Can others with the Whirlpool microwave in the 36ckts tell me how their fan operates? Thank you.

Here is a picture of mine which came broken. Notice pin on left but missing on right. When I released the retainers on the bottom, flap just fell out. As it turned out, flap and the outside shroud are all together and entire assembly had to be replaced. I understood though it wasn't too big of a deal to do.

The flap is pretty stiff to unlatch, you just have to get serious with it. Once I unlatched mine ... due to having to stand on a ladder to reach it ... it stays unlatched. If you don't unlatch it ... there is nowhere for the blower to exhaust the air.
Sebourn ... you can bow the flap itself and install a new one in the pivot holes without replacing the entire assy.

Hello Deiselguy, might be it can be bowed enough but my dealer brought one to me and tried to bow it and broke a pin just like the other one. They fixed it when I took TT in to winterize. I asked how hard it had been and was told they broke one more before replacing the whole assembly. I noticed it flexed easily but the shroud outside just gets very narrow and plastic pins do not take much to break off.
